i know this is not exactly where you post help questions but i really need it. heres my questions. I just started learning microeconomics and i am already confused. I was reading production possibility frontiers and how marginal cost and marginal benefit are related. I know that marginal...

To find the y-intercept you have to solve for y correct? Thats why you let x=0 to find the find what y is when equals 0. To find the x-intercept you have to let y be 0 and then you solve for x to determine what x is when y is 0. And Halls of Ivy maybe i should have made the question a bit...

Im having a problem with curve sketching i can't figure out how to do this problem. I am confused. Heres the question 1. For the following curve find: a)the domain b)the intercepts c)the asymptotes d)intervals of increase or decrease: local maximum and minimum e)concavity and the...

Can someone check if i did these two questions right please? The questions are: 1. A baseball diamond is a perfect square with each side measuring 90 feet in length. A player runs from the first base to second base at a speed of 25 ft/s. How fast is she moving from home plate when she is...

This is the only section so far that i don't understand, i don't know how to do some types of questions like the ones I am going to ask, can anyone please help me with these. 1. Let g(x)= x-3. Find a function of f so that f(g(x)) = x^2 2. Let f(x) = x^2. Find a function g so that f(g(x))...

I need help with these sort of questions where you have given a set of points and you must determine the equation, linear ones are easy but ones that are quadratic or cubic. So could go about and tell me how to determine equations of polynomials. Heres the set of points i am given. x...y...

I am studying for my exam for physics and i came across 2 questions that i sort of need help with. 1. Two identical spheres, with charges of Qa=-2Q and Qb=1Q, attract one another with a force of 9.0 x 10^-4 N. A third identical uncharged sphere C touches B and now C is completely removed from...

I have a question that will most likely be on my exam next week, and I am quite sure if my answer is right. Compare a 1 eV electron and 1 eV photon. List the similarities and differences. For differences there's a lot, but the main ones are an electron is a particle and a photon is a wave...

My textbook has the z-score table but it doesn't explain why the sign or magnitude means. It automatically assumes that we know. I tried searching for this information but i can't find it. 1. Explain why do normal score tables typically not include z values greater than 2.99. So can anyone...

For number 1 my teacher did tell us how to do use Permutations and combinations but i don't know how to apply it to this type of question because i have never done one before so if i were to do this instead for 1 would i be right. To get PA there are 2 ways, to get PAS there are 4 ways, then to...

I need help please with all these questions. 1. How many different paths on the diagram below will spell PASCAL? * This diagram is a little wrong because i don't know how to do it on the forums, but anyways the letters should be spaced out so that they are in between each of the spaces...

I know what the formulas are but i don't know how to describe the difference because i have this question on a lab.

I have to describe the difference between Red light and green light seen through a double slit and a single slit. Can anyone help me please?

For P i do mean Permutation. But what about my other questions

There are no answers given for these questions because they are based on my entire book. Can anyone verify my answer for this question. Solve for n 1. P(n,3)=6P(n-1,3) When i solve for n i get 3.6. 2.Determine the number of divisors for the number 3780, using the fact that a divisor...
